Abstract
Natural‐abundance ^13^C magnetic resonance spectroscopy was used for determining noninvasively the relative concentration of mono‐ and polyunsaturated fatty acids of adipose tissue in two groups of volunteers. The first consisted of subjects who had followed a fat‐reduced diet for at least half a year before the ^13^C measurements. The second were control subjects who were on a usual high‐fat diet. The ratio of unsaturated to total fatty acids in adipose tissue determined by ^13^C MRS correlated significantly with the same ratio in fat of the diet composition estimated by a dietician according to food records. The results indicate that ^13^C MRS is capable of assessing the degree of unsaturation of dietary fatty acids consumed during the preceding months.
